intussusception causes intestinal obstruction by: a. telescoping of part of the intestine into another usually causing strangulation of the blood supply. b. the loss of peristaltic motor activity in the intestine, causing an adynamic ileus. c. forming fibrin and scar tissue that attach to intestinal omentum and cause obstruction. d. twisting the intestine on its mesenteric pedicle causing occlusion of the blood supply.
